SILO.

`Application filed June 15,

To all whom 15 may concern:

Be it known that I, NIcuoLas J. Scnmcn- Tnu, a citizen of the United States, residing at Gettysburg, in the county otl Potter and State o'l South Dakota', have invented certain new and uselul lniprovehients in lSilos,

of which the lollowi'ng is a specilication,

provide a circular silo of this type so constructed as to eliminate the use, of bands or hoops for holding the body timbers together. ,'lhe invention also aims to provide a silo having a body formed of vertical timbers, the ends ot' which are oppositely beveled so that the base and cover of said silo will tend to hold the body together.

Another object of the invention is, to provide a novel method of fastening silo doors 1n position.

lvVith these and other objects in View, as shall become apparent as the description proceeds, the invention Aconsists in certain novel constructions and arrangement of parts as I sh'all hereinafter fully describe and claim.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing in which*d i Figure 1 is a side elevation ot my improved silo. Fig. 2 is a transverse sectional View taken on the plane of line 2-Q otI Fig. 1. Fig. 3 is a. longitudinal sectional View taken through one et the door openings and showing the manner in which the door is secured in position and also showing how the root is supported and Fig. fl is a sec tional view showing a portion ot the toundation vand one oii'the timbers supported thereon.

vReferring to the drawing by numerals, l designates the base or lomidation ot the silo, 2 the body, and 1) the ro t thereo'li. The body 2 is circular and 'toi-Ine( by the vertical timbers fl, which are rectangular iu crossscction and arranged with their vertical longitudinal bisecting planes in radial alinement. The inner lateral edges ot each timber contact with th i adjacent lateral edges of the adjoining timbers, which arrangement pro- Specicaton of Letters Patent.

vides a continuous,,interior wall. The Side 'laces o ot the timbers 4t form outwardly extending dlhedralangles which are lilled With a 4.suitable packing (3 such as cement or other 60 waterproo'lE materia-l. It is not necessary that thisl packing ,should entirely till the p.iin 's between the faces ot' the timbers but may extend inwardly only a short distimbers l are held together by the spikes 7, each .spike extending through one timber and partly through an adjoining timber.

The lower ends ot the timbers -l are bereled downwardly and invardly and rest upon the inclined surtace 8 ci the 'foundation l. This inclined surface 8 is wider than the timbers 4 so that theymmay' worlt inwardly a slight distance but areprevented tronrworking outwardly by the vertical wall 9. The upper ends oit the timbers l: are beveled downwardly and outwardly and .support the conical rootl 3. It will be seen that the weight of this roof also tends to draw the body members o1' timbers 4 in- 80 wardly.

A plurality of alined openings 10 are formed in the bod-y 2 by cutting away at intervals portions of a number of successive timbers t. These openings provide en- 35 tra'nces into the silo and are normally closed` by the doors ll which any suitable manner. Fasteners 12 are pivolally secured on a line with the vertical centers o't the doors-by the bolts 13. Each 9o fastener is formed with an opening in its out-er end which receives a pintle 14 that passes through spaced ears formed onv the bolt 13. The ends of the fasteners 12 engage over the cross bars 15 which are secured 95 transversely ot' the openings l0. The ends ot each cross ,bar are secured in inortises or notches termed in the outer edges of the uncut timbers forming the said walls ot the openings. 10.. ot each door, the leverage of the clutch or fastener 1Q and the pressure of they contents ol' the silo all combine and tend to hold the door securely in position over the openings l0 in close contact with theinterior silo. lt. will be seen that this construction of silo door and the manner of fastening it in position is such as to provide a continuous and essentially unbroken interior sur- 'lfaee tor the silo which will be tree from any 11o tance. The inner contacting edgesot' the 65 may be constructed in lt will be seen that the weight of the be easily opened by moving .same-vertically butmay'make such modifications as fallin a suliicient distance "to relieve the fastener the scope and spirit of the invention, as de- 12 of any pressure' after whichisaid fastener fined by the appended claim. may be removed from the cross bar 15.
